Attaochu was originally drafted by the Chargers in the second round of the 2014 draft. He played 38 games the past four seasons with 92 tackles and 10 sacks, including six in 2015. He struggled the past two seasons and played only four games in 2017 for the Chargers.

General manager John Lynch called Attaochu a disruptive player who can contribute on defense and special teams.
